1. A rapid pulsatile smoke extraction system comprising:
a laser handpiece including a sleeve configurable to be applied to tissue;
a vacuum pump and a vacuum reservoir;
a conduit connecting the reservoir with the sleeve; and
a valve inserted in the conduit,
wherein a volume of the vacuum reservoir is at least two times larger than a volume of the sleeve, such that operation of the valve supports instantaneous evacuation of smoke and particulate products from the sleeve into the vacuum reservoir,
wherein the valve is constructed and arranged to open communication between the sleeve and the vacuum reservoir just prior to start of a laser pulse and to close communication between the sleeve and the vacuum reservoir just after end of a laser pulse.
